Testimonials & Reviews

"What was the biggest influence on your decision to purchase Efficient Calendar? My answer: acceptable price; no mail client (I purchased a different program for that so didn't need this feature in the calendar software); Please write down your comments on Efficient Calendar. My answer: I think the program has a simple, convenient and very managable layout which is definitely its asset."

- Kinga Kocimska, April 2012


"... Please write down your comments on EfficientPIM. My answer: I haven't learned all I need to know yet about your program but I find it easy to navigate and easy to learn. ... Because I can't specify fields to export, I now have to "tweak" the exported data, which requires a lot of extra work. Another Problem: In Contacts, Tools, Options, I set the Home Address as the default mailing address; but this only works for new contacts added; there's no way that I can see to apply that change to all existing contacts. ..."
